shifter-comb 5 from side to side carries the warp-threads over against the separators alternately as the needles rise and fall, first on one side of theneedle and then on the 5 other. This lateral pressure tends occasionally to deflect the separators and also the needles, so as to close up the space which should be present on the farther s de of the needle. This absolutely prevents the warp from being brought down into cooperation with the pile-thread. By my construction,

however, this difliculty is avoided, since the needles are always guided just below their points and always present the proper spaces r for the passage of the warp-threads. Since the effective length of the needle is substan tially the same as its upward stroke, and since the guide member must always remain below the warp-thread, I have'mounted the guide member 20 in such a manner that it may have a relatively stationary position while the needle is in the upper part of its stroke. Normally the ends of the guide member 20 rest in the yokes 21 on the sides of the guide-frame 2.

22 is a yoke carried by one end of the needle-frame, which picks up the guide member 20 just before the needles reach their uppermost position and carries it through the remaining upward movement of the needleframe. Of course the guide at this time is a considerable distance below the eye of the needle; but there is no lateral strain upon the needle at this time, but only when the shifter comb is operatingnamely, while the pilethread is below the warp-thread.

23 is a slotted guide-bar loosely supporting the upper ends of the separators 14.

24 is a cap ont he front of the guide-bar 23 for preventing the separators from falling out toward the front. The upper ends of the separators are not, however, held rigid by this bar, but are allowed considerable freedom of movement as they must have when the separators are laterally moved by contact of the shifting warp threads. The separators may, moved for the purpose of repair or replacementwithout interfering with the other parts of the mechanism.

Other advantages than those set forth herein will be apparent to those who are skilled in the art without further description. It may be stated, however, that the use of my invention makes it possible to operate a loom of this character with a laterallymoving warp-threadfor pro ducing a long-pile weave for instance, like the oriental weavewhich it has not before been possible to accomplish 60 with any degree of certainty.

however, be readily re-.

What I claim is 1. In a pile carpet or rug loom having a vertical and horizontal shifting movement of the warp-threads, a set of vertically-operable needles, flexible separators between the needles and a rigid slotted guide for said needles located below the position of the warp threads to prevent relative lateral displacement of the needles.

2. In a pile carpet or rug loom having a relative horizontal shifting movement of the warp-threads, a set of verticallyoperable needles, a rigid slotted guide therefor located below the position of the warp-threads, and I means for permitting relative upward move- 7 5 ment of the guide at the upper part of the stroke of the needle.

3. In a pilefabric loom, a series of vertically-movable {needles for carrying the pilethreads and flexible separators between the needles for cooperating with relative laterally-shifting warp-threads, and means for guiding said needles below the warp-threads and preventing relative lateral displacement. 5

4. In a loom for pile rugs and carpets hav ing laterally-shifting warpthreads, the com bination of a set of vertically-movable needles for carrying the pile-threads, a set of separators for guiding the warp-threads, and means for cooperating with the needles below the warp for preventing lateral displacement of the points of the needles when the warp-threads are being laterally shifted.

5. In a pile rug or carpet loom, a needleframe having a series of needles, a support therefor comprising three slotted bars forming a pocket, a pin extending through said needles and a metallic composition filled in between said bars and said needles.

6. In a pile rug or carpet loom, the combination of a series of vertically-movable needles, a support therefor, flexible separators for the warp-threads arranged between the needles and a pin or rod passing through said 1 5 needles for supporting said separators inde pendently of the needle-support.

7. In a loom for Dile carpets and rugs, having vertically shifting warp threads, the combination of a set of vertically-disposed no needles for the pile-threads, a series of vertically-disposed flexible separators arranged alternately with the needles, means for supporting the lower ends of the separators and a slotted bar or guide for loosely holding the I I 5 upper ends of the separators in position.
